A security transaction risk control system, method and device

PendingCN122453515ARisk ControlMACD
This invention discloses a securities trading risk control system, method, and device. The system acquires multi-source data in real time, including market data, public opinion, financial reports, industry cycles, government subsidies, executive backgrounds, and liabilities. It generates a sell unlock threshold through a dynamic benchmark return model, triggering mandatory manual confirmation on the client side when the profit rate reaches the target. In parallel, a risk identification module calculates a dynamic anomaly threshold X = industry volatility × 3 + market sentiment coefficient, and independently determines whether the stock price volatility exceeds the threshold, the industry is in a downward trend, there are losses with dividends, there is government / business dependence, there is a high debt ratio, or there is insolvency. Securities that meet these criteria are added to a gray list with tiered warnings and are prohibited from purchase. Securities with falsified financial statements are permanently added to a blacklist and prohibited from purchase. Daily, the system performs a technical pattern scan on securities excluded from the black and gray lists, automatically generating a red list based on bullish moving average alignment and MACD golden cross divergence conditions. The system pushes the blacklist, gray list, and red list data to the client APP in real time. The client directly displays the list status through a built-in rendering engine: blacklist securities are rendered with black labels, graylist securities with gray labels, and red list securities with red labels. Other securities are displayed normally. Users can intuitively view the classification status of each security on the APP interface. This invention solves the technical problems of existing trading systems lacking automatic risk interception and high-quality target identification capabilities by using automated data acquisition, dynamic threshold algorithms, forced interface control, multi-period technical indicator fusion, and blockchain notarization.

Reservoir water storage induced reservoir bank landslide prediction method and system based on refraction principle

This application discloses a method and system for predicting reservoir bank landslides induced by reservoir impoundment based on the principle of refraction. The method includes: obtaining the natural slope angle above water in the natural state and the stable slope angle underwater in the saturated state of the target reservoir bank slope; introducing and calculating the refractive index to characterize the degree of difference between the natural slope angle above water and the stable slope angle underwater; the introduction of the refractive index is based on the understanding of landslide mechanisms: during reservoir impoundment, the water surface acts as an interface for abrupt changes in the physical and mechanical properties of the soil and rock mass, leading to a discontinuous reconstruction of the slope's stable morphology with the water surface as the boundary. The reservoir impoundment process follows the principle of mass conservation, and the actual inclination angle of the failure surface, instead of the natural slope angle above water, better reflects the mechanical state of the slope during instability; based on the value of the refractive index, the instability risk and progressive failure range of the target reservoir bank slope during reservoir impoundment are qualitatively or quantitatively predicted. This application improves the early risk identification and dynamic warning capabilities for reservoir bank landslides induced by impoundment.
